Diaphanoscopy: indications, technique, effectiveness


Diaphanoscopy, or transilluminate is a method of visual inspection of the soft tissues based on the ability of the latter to pass visible light. Different tissues of the body have differences in transmissive ability for light waves: the fluid or the air can reflect light, but other tissues significantly delay it. This allows you to use a similar procedure for the detection of free fluid or the formation of capsules inside the organs. However, even different types of fluid (serous, purulent, or hemorrhagic) have differences in ability to transmit light that can be used for differential diagnosis. The most popular two methods of transillumination – diaphanoscopy of the scrotum and the eyeball.

A similar study is performed using special light sources, not the heating of biological tissue.

Description of the procedure

Diaphanoscopy eyes or scrotum is based on the use of special devices that create a focused beam of light. The attending physician directs it to the biology education and values change its intensity. Different objects (testicle, the eyeball, the accumulation of fluid) differ in their ability to transmit visible light that forms the basis of the entire method.

The holding of such examination is possible using a special device diaphanoscopy. It is a specially curved or straight tube having at one end a source of visible light. Depending on the task, the attending doctor may choose diaphanoscopy various sizes, diameter and intensity of the visible light. It’s also possible to use conventional endoscopes, but when applied you can’t be 100% sure of the objectivity seen pictures.

Indications for

Diaphanoscopy used for diagnosis of various diseases of organs located externally with the possibility of scanning. Often transillumination of the used in the following situations:

  • In ophthalmic practice, with the help of scanning of the eyeball, eyelids and okolovrusno fiber it is possible to identify a number of diseases. For example, this method can be used for the diagnosis of benign and malignant tumors in the tissues of the eye socket, bleeding into okolovrusno fiber, etc.
  • The second application area of the diaphanoscope, is urology. This method is an excellent choice for the diagnosis of diseases of the penis, and often scrotum. Transilluminate allows to detect tumor growth, ascites, varicocele, and other pathological processes.
  • Diaphanoscopy is used for the diagnosis of ENT diseases, especially in cases of sinusitis and sinusitis with the impossibility of performing an ultrasound examination. Passing through the soft tissue of the light allows to detect accumulations of pus, expansion of the tumor tissue, and to study the condition of the sinuses and forehead. In studying the condition of the soft tissues of the nose, diaphanoscopy may be the most suitable method.

  • The study of soft tissues of the breast may also be performed by using a diaphanoscope with the unavailability of ultrasound studies. With transmitted light it is possible to identify the nodal entities, or to assess the condition of the implants.

Indications for examination transilluminate determined by your doctor. The method has no contraindications, with regard to its overall safety and lack of impact on the patient.

Diaphanoscopy scrotum

The most important application field of transillumination diagnosis of diseases of scrotum and testes, in particular, by increasing their size. The method is suitable for conducting differential diagnosis of hydrocele (hydrocele) with other diseases.

Of hydrocele in his skins begins to accumulate free fluid from the abdominal cavity, which leads to an increase in eggs, and, as a consequence, one half of the scrotum. When diaphanoscope, due to the fact that the fluid is of a serous nature and is completely transparent, scrotum glows bright red due to the high permeability to visible light.

  • A similar procedure can be used for differential diagnosis of hydrocele from a tumor, inflammation (orchitis, epididymitis), or swelling of the skin. In all these cases, the light will not pass through the tumor.

  • Diaphanoscopy great for quick diagnosis in case of doubt about the hydrocele or inguinal hernia.
  • The method has proven itself in the postoperative period, when the attending physician must assess the condition of the sutures, the membranes of the testicle.
  • Also, transilluminate can be used to detect foreign bodies and concretions in the ducts.

Diaphanoscopy allows you to visually assess the uniformity of the soft tissues with the help of a passing beam of visible light.

Survey methodology egg with transillumination is very simple and can be done by your doctor. The procedure is performed in a dark room using diaphanoscopy is a special device capable of producing a focused beam of light. The doctor puts diaphanoscopy to the scrotum and holding it against the skin explores her soft tissue. After this it is necessary to carry out the interpretation of the results and, if necessary, to determine further diagnostic tactics.

The process is low cost and can be used as a routine method for urological examination. The average cost of the procedure – 600-700 rubles in various hospitals.

Diaphanoscopy eyes

Eye study with transillumination is carried out through the sclera after prior local application of anesthetics. In the case of using this method in children, General anesthesia is necessary. The procedure is also carried out in a darkened room that allows to improve the results.

After anesthesia, diaphanoscopy gently bring to the conjunctiva and moved over its surface, constantly control the pressure force. The attending physician evaluates the intensity of fluorescence through the pupil. If visible light is uniform and bright, the structure of the eyeball is homogeneous, indicating the absence of pathology. If there are areas with lower intensity of illumination, before diaphanoscopy is education, poorly light-transmissive (tumor, cyst, site of hemorrhage, etc.). After that, as a rule, appoint additional methods of research for diagnosis.

Interpretation of the results should be made only by the attending physician taking into account the patient’s complaints and clinical data.

Holding diaphanoscope allows early diagnosis to detect a pathological process in the eyeball, scrotum, breast and other soft tissues. Change the intensity and brightness of light in the survey indicates the presence of pathological processes. The procedure does not harm the patient and therefore can be used at any age as a screening method.
